WebJun 6, 2014 · Once the bacteria feed on the iron, it turns to rust, and that rust can grab onto stuff floating by – like arsenic, other harmful metals, even viruses. In other words, these bacteria can actually help filter water. And that rust – it’s remarkably delicate. Microbiologist David Emerson (Photo: Ari Daniel Shapiro) FIELD: I do find it beautiful.
Iron-oxidizing bacteria (or iron bacteria) are chemotrophic bacteria that derive energy by oxidizing dissolved iron. They are known to grow and proliferate in waters containing iron concentrations as low as 0.1 mg/L. However, at least 0.3 ppm of dissolved oxygen is needed to carry out the oxidation.
